To ttZZ whom it may concern.-

Beit known that I, ABRAHAM L. SHIPMAN, a citizen of the United States ofAmerica, residing at Fulton, in the county of Bourbon and State ofKansas, have invented certain new and useful Improvements in CornPlanters; andI do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements incorn-planters; and it consists in the special construction and combination of the parts, as will be hereinafter fully set forth, andspecifically pointed out in the claims.

In the accompanying drawings, which illus trate my invention, Figure 1is a perspective View of a corn-planter constructed in accordance withmy invention Fig. 2 is a plan View, and Fig. 3 is a sectional view takenon the line :0 m of Fig. 2.

A refers to the front portion of the main frame,which consists oftransverse bars a and a, which are rigidly connected to each other bylongitudinal bars I; b. To the under side of the bars a and a arerigidly attached runners B B, the rear vertical portions of whichterminate above the seed-openings formed in the ends of the bar a. I

0 refers to a transverse axle, which. is attached to the bar a of theframe A by means of metallic plates, which are rigidly secured thereto,the end of said plates being bent so as to form eyes which encircle theaxle or shaft 0, said plates being indicated by the letter D.

E E refer to the seed'hoppers, which are secured to the ends of the bara, said bar a hav ing vertical openings immediately above the heel ofthe runners, through which the seed is discharged from the hoppers Ewhen the seedslide F is reciprocated. The seed-slide F is provided withopenings, two at each end, and above said perforated ends a bar extends,said bar being secured to the hoppers immediately above said seed-slide.The seedslide F enters recesses or Openings in the sides of the hoppers,so as to retain the same in position, and an excessive lateral movementthereof is prevented by a pin, f, which projects upward from the bar a,said pin entering a slot, f, in the seed-slide. The seed-slide F hasrigidly secured thereto two upwardly-projecting pins, g 9, upon whichare mounted frictioirrollers, said pins being connected to each other attheir upper ends by a cross-piece, g.

The outer ends of the shaft or axle 0 have rigidly mounted thereonwheels H H, from the rims of which projectbent bars or markers h, theopposite ends being secured to the hubs of the wheels, as shown.

A refers to the rear frame, which is pivotally attached to the forwardframe, A, by a flexible coupling, 2', so that the frames may swingvertically with respect to each other. This rear frame has mounted onits transverse axle covering-wheels Lwhich will be on a line with therunners B, and at a suitable point. Said frame carries averticalupright, J,which is bifurcated at its upper end, within which bifurcatedportions is journaled a sprocketwheel, K,which is rigidly attached toits supporting-shaft, said shaft also carrying a crankhandle, 70.

The axle or shaft 0 has rigidly attached thereto a sprocket-wheel, K,over which a belt, K, passes, for connecting the sprocketwheels K andKto each other. These sprocket-wheels and belts are for the purpose ofrotating the wheels H, so as to bring the markers to the properposition, so as to indicate where the seed has been dropped.

If desirable, the sprocket-wheel K may be provided with a spring-clutchor equivalent device for throwing the same in and out of gear, so thatit will remain idle when it is not needed for adjusting the position ofthe wheels H.

L refers to a sprocket-wheel, which. is rigidly mounted on the axle O,and on a line therewith in front of said axle sprocketwheel L issecured, which sprocket-wheel is supported by a bent bracket, llLwhichbracket has a curved portion, m, through which the projecting sidepieces, N, on the sprocketchain L may pass when said belt is rotated.This sprocket-wheel may have two or more angular projecting side pieces,N, on opposite sides, said angular pieces being adaptedrto contact withthe anti-friction rollers on the vertical pins n, so as to reciprocatethe seedslide.

The operation of my invention is as follows: When the machine is drawnforward, the wheels H will rotate and cause a rotary movement of thebelt L, having the angular side projecting portions, N, which willalternately strike against the opposite vertical anti-friction rollers,so as to cause the reciprocation of the said slides. If .the markersshould not correspond with the dropping of the seed they can be turnedby the crank-handle It, so as to bring them to a proper position.

1. In combination with acorn'planter, having a reciprocating seed-slidewith vertical pins attached thereto, a sprocketchain having angular sideprojecting pieces, N, attached r to, b a k M, a ry n a p o k t wheel andprovided with a bent portion, m, theaxle O, with driving-wheels,and asprocketwheel over which said belt passes, substantially as shown, andfor the purpose set forth.

2. In combination with a corn-planter, the frames A and A, pivotallyhinged to each other, a shaft, 0, carried by the forward frame andprovided with sprocket-wheels L and K, a belt geared to a sprocket-wheelon the rear of the frame with a crank-handle for rotating said shaft,the sprocket-wheel L being connected by a. belt with side projectingpieces which abut against vertical pins on the seeds lide, so as toreciprocate the same, and a bracket having a return-bend, through whichsaid side projecting pieces may pass, said bracket carrying asprocket-wheel, the parts being organized substantially as shown, andfor the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
